Gauged inverse seesaw from dark matter
Abstract We propose an economical model addressing the generation of the Inverse Seesaw mechanism from the spontaneous breaking of a local $$U(1)_{B-L}$$ U ( 1 ) B - L , with the Majorana masses of the sterile neutrinos radiatively generated from the dark sector. The field content of the Standard Mo...

| Summary: | Abstract We propose an economical model addressing the generation of the Inverse Seesaw mechanism from the spontaneous breaking of a local $$U(1)_{B-L}$$ U ( 1 ) B - L , with the Majorana masses of the sterile neutrinos radiatively generated from the dark sector. The field content of the Standard Model is extended by neutral scalars and fermionic singlets, and the gauge group is extended with a $$U(1)_{B-L}$$ U ( 1 ) B - L and a discrete $${\mathbb {Z}}_4$$ Z 4 symmetries. Besides dynamically generating the Inverse Seesaw and thus small masses to the active neutrinos, our model offers two possible dark matter candidates, one scalar and one fermionic, stable thanks to a remnant $${\mathbb {Z}}_2$$ Z 2 symmetry. Our model complies with bounds and constraints form dark matter direct detection, invisible Higgs decays and $$Z'$$ Z ′ collider searches for masses of the dark sector at the TeV scale. |
